I would try the spring avenue and possibly reclean the valves with a cleaner/degreaser like Alsyn or Hetman. They remove that fine layer of dust and grime that Jay mentioned. Also use the cleaner on the linkage and bearing parts. You might also try a different viscosity of oil. A lighter oil will help parts with tighter tolerances and may not build up as quickly. You probably already know this, then please ignore the rest of this post and don't be insulted. The back plate of the rotor, if put on at the slightest of angles or is tappen in too far, will restrict the movement of the valve. I would consider lapping the valves a last resort, because, obviously, you can't put metal back once it is removed. Hope they speed up.
